Many thanks. Indeed "-fix" does several changes, but also to other 
volumes/accounts (so will have to check whether these were 
accessible/reported as corrupted before or not, and dump+compare the 
VLDB entries just in case..).

1.6.10-2 does not fix things "differently" in our case (same md5sum on 
the resulting DB file)
